Study Summary
Cocaine abuse is an unrelenting public-health concern. Behavioral therapies are considered the "standard of care" for reducing cocaine use and preventing relapse. However, even with intense behavioral interventions, rates of relapse to cocaine use are discouragingly high (i.e., 60-95% of patients return to drug use). Novel strategies are urgently needed to improve treatment outcomes for cocaine-use disorders. The overarching goal of this project is to assess the feasibility, acceptability and initial efficacy of an innovative cocaine-based inhibitory-control training procedure. This goal will be accomplished through the conduct of a Stage I pilot trial. Cocaine-dependent participants will be enrolled and randomized to receive inhibitory-control training to cocaine or neutral images (N=20/condition). This proposed intervention, cocaine based inhibitory-control training, will be delivered using an innovative computer program which teaches cocaine abusers to inhibit a pre-potent response to cocaine or neutral cues. The primary hypothesis is the proposed procedures are feasible and acceptable to the participants. Feasibility will be assessed by determining time needed to enroll the target sample; adaptive randomization outcomes; participant attendance, completion and adherence to study procedures. Acceptability will be determined using a Treatment Acceptability Questionnaire. The secondary hypothesis is that participants receiving cocaine-based inhibitory-control training will reduce their drug use to a greater extent than their counterparts in the neutral-image condition. Reduced cocaine use will be demonstrated by fewer positive-urine samples using qualitative urinalysis and a reduction in levels of benzoylecgonine as determined by quantitative urinalysis (i.e., ELISA). The third hypothesis is that participants receiving cocaine-based inhibitory-control training will show improved inhibitory control and neurocognitive functioning relative to their counterparts in the
Primary Outcome
Response inhibition and response execution will be measured using a stop-signal paradigm using a choice reaction time task that engages participants in responding to go-signals when stop-signals occasionally inform them to inhibit the response.
